Parrot Deprecations

This page exists to systematically document all deprecations that apply to core Parrot code. We don't hate our users and while we love ripping out crufty old code, we also don't want anyone developing code on top of Parrot to dread paying the "upgrade tax" when moving from one supported version to the next. The idea behind this page is that by following the instructions for each version transition, developers of HLLs and libraries can have a well-known and deterministic upgrade path.

Any new deprecations must be described on the appropriate page and summarized here before being committed to trunk. This deprecation policy will be instituted shortly before the 2.6 release. Although we will attempt to add notices for previous version transitions, these lists may be incomplete. Notifications for the 2.6->2.9 transition and later will be complete.

For instructions on how to deprecate Parrot code, please see HowToDeprecate.

Changes Between 2.9 and 3.0

This list is a summary. A more complete description and migration path for each change is at ParrotDeprecationsFor3.0. Any deprecations occurring after the 2.9.0 release require an accompanying notice on this page and here, so the list should be exhaustive. If you find a deprecation that should be listed here, file a ticket here or hop on #parrot on irc.parrot.org and let us know.

Changes Between 2.6 and 2.9

This list is a summary. A more complete description and migration path for each change is at ParrotDeprecationsFor2.9. If you find a deprecation that should be listed here, file a ticket here or hop on #parrot on irc.parrot.org and let us know.

Changes Between 2.3 and 2.6

This list is a summary. A more complete description and migration path for each change is at ParrotDeprecationsFor2.6. Because this list was created after the deprecations were committed to trunk, it's likely we've missed a few. If you find a missing deprecation notice, file a ticket here or hop on #parrot on irc.parrot.org and let us know.
